Artemis VST: Small CPU overload on the very first Note

Not a bug in renoise but most of the time this VST “benoit serrano: Artemis”
makes a little pause when the first note is played.
Mostly I activate the static buffer and it’s alright, but I can’t get this one to work properly.

It probably has to initialize much more than just filling buffers as it seems…

It is a synth edit plugin so i wonder if the static buffer stuff has influence. I thought these plugins usually also crash with multiCPU environment, this feature should be turned off by default though…
